The invention relates to a method for dyeing fabric with a natural mineral dye. The method comprises the following steps: (1) modifying fabric with a modifying agent by a dipping or padding method for use; and (2) nanocrystallizing the natural mineral dye with a dispersing agent, preparing the nanocrystallized mineral dye into a dye solution, dyeing the modified fabric by a double-dipping and double-padding method, and drying, baking, soaping, rinsing and drying the fabric. The method for dyeing the fabric with the natural mineral dye is simple and feasible; and by the method, the color fastness of the natural dye is improved, the functionality of the natural dye is improved, and dual purposes of high-color fastness ecological dyeing and functional finishing of the natural dye are achieved. |
